Methodological advances: using greenhouses to simulate climate change scenarios.

摘要: Human activities are increasing atmospheric CO2 concentration and temperature. Related to this global warming, periods of low water availability also expected increase. Thus, concentration, temperature three the main factors related climate change that potentially may influence crops ecosystems. In report, we describe use growth chamber – greenhouses (GCG) gradient (TGG) simulate scenarios investigate possible plant responses. GCG, set act simultaneously, enabling comparison a current situation with future one. Other characteristics GCG relative large space work, fine control humidity, fertirrigation possibility light supplementation, within photosynthetic active radiation (PAR) region and/or ultraviolet-B (UV-B) light. TGG, above-mentioned can independently or in interaction, more mechanistic studies aimed elucidate limiting factor(s) responsible for given response. Examples experiments, including some study acclimation, phenomenon leads decreased capacity under long-term exposures elevated CO2, using TGG reported.
